mcnnm roa MAKING nun FINISHING GLASS BARS, nons, 'rmms, no'r'rnn NECKS,

AND rim LIKE.

-ppllcation fled September 5, 1925. Serial No. 54,786.

To all whom it may concern:

- Be it known that I', Vwron DUBAND, J r., a citizen of the UnitedStates, residing at Vinela'nd, in the county of Cumberland and 5 Stateof New Jersey, have invented certain new and useful Im rovements inMachines for Making an Finishing Glass Bars, Rods, Tubes, Bottle Necks,and the like, of which the following is a specifica- I0 tion.

My invention relates to an im rovement in machines for making and finising glass bars, rods, tubes, bottle necks, and the like.

This invention consists in mechanical means for feeding the articlessuccessively th-rou h the machine, where their ends are heated andrendered semi-plastic preparatory to being fashioned into the s ape de 1sired after which they are conveyed in' similar ashion to someconvenient point for handling.

In the accom anying drawings.

Fig. 1 is a iagrammatic view in side elevation of the machine;

Fig. 2 is an end view;

Fig. 3 is an enlarged fragmentary plan view; and

Fig. 4 is an end view.

The glass articles, or, as illustrated, the rods 1- are placed in ahopper 2, and fed down by gravity upon the. two screws 3 and 4, whichare provided with gears 5 and 6 respectively to turn inv unison and inopposite directions by reason of the two intermediate gears 7 as viewedin Fig. 2.

The pitch 0 these screws 3 and 4 changes from one end to the other, sothat the articles 1 are spread apart .as shown in;Fig's.' 1, 3 and 4.

While being conveyed forward, the ends of the bars or other articles 1pass through the glor -holes 8 as viewed in Figs. 1 and 2, w ere the aresoftened by the heat of the furnace. hese glory-holes are heated to there uired degree in any approved manner, as or instance by the burners 9,of which there may be any number.

Upon reaching the right-hand end or annular passage through the machine,an operator molds the ends of the rods, formi the heads 10 thereon, ifthey are to be use as towel-bars or the like. It is obvious, however,that they may be fashioned into y i P at this point. They are thencarried to a lower level by the conveyor 11 to screws 12 and 13 similarto the screws 3 and 4, which screws are provided with ears 14 and 15which are driven respectivey by the gears 5 and 6 on the screws-3 and 6respectively. Thus the lower conveyer-screws 12 and 13 areturned in adirectlon just the reverse of the screws 3 and 4, so that the articles 1thereon are conveyed back in the opposite direction through [the machinebeneath the gloryholes. There they 0 to the end where they started,after w ich they are slid off on a conveyor 16,as shown in dotted linesin Fig. 2.

It 1s evident the. the rods or bars or other articles bein treated mayhave a slight tendency as they move forward arallel to move slightlyendwise back and orth, as has been in'icated in Fig. 3; but the maintravel is transversely forward in a contin-- uous movement which soarates them due to the change of itch o the feed or conveyer-screws 3 an4 as their ends become soft to prevent contact with one another. This isrepeated in-the lower level on the various screws 12 and 13, asillustrated in Fig. 1, to give the bars a chance to cool while runningthrough the furnace, and it is not until they are sufficiently cool tomakecontact with. one .another safe, that the itch ofthe screws changesa little prior to t eir reachin their ,destination at the feed orleft-ban end of the machine as viewed in Fig. 1.

A sim 1e and inexpensive method is thus provided for the treatment ofglass articles, they in. this manner and b the rovision of this machinebeing nishe in a single passage through the m hine or furnace.

I claim:

- 1. Means of the character described in eluding-feed screws of varyingpitch turning in opposite directions to carry articles placed thereonuniformly lengthwise thereof and to se arate, them at predetermined.points int eir travel from one another.

2. Means of the character described including feed screws of varyingpitch turning in opposite directions to car articles placed thereonuniformly lengthwise thereof and to separate them at predeterminedpoints in their travel from one another, and

heating ineansthrough which the ends of;

the articles pass as they are fed by the screws.

ingthreads pitched to gr 3.Means of the character described includingtwo sets of conveyer-screws, the threadsof which vary in width somewherethroughout the length of the screws whereby to feed the articleslengthwise thereof and separate them from one another at determinedpoints, means for applying eat to the ends of these articles tosoftenthem, conveyer screws for turnin the articles having threadspitched to gra ually bring them 'tOgether just prior to their. dischargefrom the conveyer. 4. Means of thecharacter described inclnding two setsof conveyer-screws, the threads of which vary in width somewherethroughout the length of the screws whereby to feed the articleslengthwise thereof and separate them from one another at redeterminedpoints, means for applying eat ton'th'e ends of these articles to softenthem, elzmveyerscrews for turning a ually bring them the articleshavmomen together prior to their discharge from the conveyer, a meansfor conveying the articles 'from o e set of conveyer screws to the otherset."

5. Means of the a character described including two sets of conveer-screws, the threads of which vary in width somewhere throughout thelength of the screws whereby to feed the articles lengthwise thereof andseparate them from one another at v determined points, means forapplying t to the ends of these articles to soften them,

conveyer screws for turnin the articles having threads pitched togragually bring them together just prior to their dischar e from theconveyer, and gearing for causing two of the conveyer screws to' turn-inunison in opposite directions, and the other two conveyer screws inunison in reverse direction, whereby the articlesare fed first throughthe machine in'one' direction, and then through the machine in theopposite direction.

In, testimony whereof I aifix m si nature.
